Complaints of stalling engines on certain 2012 BMW K1600 GT and K1600 GTL motorcycles has lead the manufacturer to issue notices to owners instructing them to return their vehicles to an authorized repair facility to have the problem fixed.

According to reports filed with the NHTSA, the problem dates back to August 2011 when BMW received the first complaint of an engine stalling on a K 1600 GT in Europe. Further complaints and an investigation revealed that the calibration threshold within the throttle valve control software is overly sensitive and could result in incorrect signals sent to the engine control unit (ECU). The ECU may initiate a “fail safe mode”, limiting the engine speed to 2,000 rpm and in rare cases stalling the engine completely.

BMW will correct the problem by updating the throttle control software. Approximately 2, 475 vehicles could be affected. Owners wanting more information about the defect can contact BMW customer relations at 1-800-525-7417 or email BMW at CustomerRelations@bmwusa.com. The NHTSA Campaign Number is 13V-526.
